Minor alloying addition of Ag improves the hydrogen storage capacity and reduces the dehydrogenation temperature of the amorphous Mg65Cu25Y10 alloy. Hydrogen storage capacity is increased from 2.1 wt% to 3.2 wt% when substituting Mg by only 1 at% of Ag. After hydrogenation, the amorphous Mg-Cu-Y(-Ag) alloys decompose into two types of sites for hydrogen occupations: i.e. a new amorphous Mg-Cu(-Ag) hydride clusters and YH3 nanocrystals. This study shows a simple method to tailor hydrogen storage properties of amorphous Mg65Cu25Y10 alloy.
